- PX Uncle John (concerned that it's maybe a bit heavy)
- Merida CX (from Paul Milnes via ebay)
- Kinesis Pro 6 - Slightly over budget and availability seems to be an issue at the moment
- Genesis Vapour Disc (but not available as a frame/fork alone)
- Various Chinese ones (as per my earlier thread) - probably fine but may take a long time

I've got an Uncle John. It doesn't seem overly heavy. Not tried it with discs yet. The Planet X fork to go with the frame isn't disc compatible so I paired up the frame with an alloy Kinesis CX Disc fork instead. It was less than £70 when I got it and no heavier than the majority of carbon CX forks that can take a disc brake. It is actually a very good match with the Uncle John.

I may be sticking on discs later this year once I decide I can justify buying another set of wheels.

van dessel gin and trombones, carbon and aluminium, full carbon fork and discs, however out of your price range ( although if you give thebearded man a ring he will probably knock something off the list price. Fantastic bikes btw.

Agree there are some good options from German shops but I emailed several of them and none were willing to ship to the UK.

Paul milnes also have Forme frames available - I was in the same situation as the OP and went for a Merida from them. In the process of building it up now but looks like it will do what I'm after (apart from the Euro graphics on the frame).

Yeah, the graphics are a bit Euro though I could maybe get used to that

How does the frame seem? Hard to tell really from the pics alone. Don't suppose you have a weight for it? I'm a bit suprised that it has a standard headset - makes me wonder if it's a bit of an old design.

Clubber - I haven't weighed it yet but can do an approx weight for you - mines a fair bit smaller than your size though. I was tempted by some more expensive options (Kinesis is probably the nicest of the sub £500 IMO, the rest are much of a muchness) but didn't want something too smart as my current cx bike tends to get used for everything from quick spins to touring, roads to caddon bank at innerleithen. Headset not a worry for me - cheaper for replacements in the future. Paul Milnes were helpful on the phone and did a decent deal.

OK Clubber, Mrs bajsyckel's digital baking scales have the forks in at 659g with a (way too) long steerer and crown race/sfn/topcap/bolt. The frame (plus seatclamp, FSA headset two lengths of cable outer and guides, and a little chain guard thing) weighs in at 1725g. That's all a rough guide - I don't vouch for the accuracy and the frame is a 52. Just need to decide on some drops for it and it'll be getting built up.
